The internal form is an - * object having <code>get</code> and <code>opt</code> methods for accessing - * the values by name, and <code>put</code> methods for adding or replacing - * values by name. The values can be any of these types: <code>Boolean</code>, - * <code>JSONArray</code>, <code>JSONObject</code>, <code>Number</code>, - * <code>String</code>, or the <code>JSONObject.NULL</code> object. A - * JSONObject constructor can be used to convert an external form JSON text - * into an internal form whose values can be retrieved with the - * <code>get</code> and <code>opt</code> methods, or to convert values into a - * JSON text using the <code>put</code> and <code>toString</code> methods.

An <code>opt</code> method returns a - * default value instead of throwing an exception, and so is useful for - * obtaining optional values. - * <p> - * The generic <code>get()</code> and <code>opt()</code> methods return an - * object, which you can cast or query for type.

Instead, they return a specified value, such as null. - * <p> - * The <code>put</code> methods add or replace values in an object.
